Ghnaya, Imed. "Résilience de la perception collective et augmentée des véhicules autonomes connectés par les C-ITS". Electronic Thesis or Diss., Bordeaux, 2024. http://www.theses.fr/2024BORD0068.
Texto completoCooperative Intelligent Transport Systems (C-ITS) represent an advanced approach in modern transportation. They leverage communication technologies, such as ETSI ITS-G5 and Cellular Vehicle-to-Everything (C-V2X), to enhance road safety and traffic flow. Central to C-ITS is the concept of cooperative perception, a transformative feature that enables Cooperative and Autonomous Vehicles (CAVs) and roadside infrastructure units to share and collectively analyze data from various sensors, including cameras, lidar, and radar. This cooperation is facilitated through the exchange of Cooperative Perception Messages (CPM), which provide a high-level description of detected road objects, via communication networks. The primary objective is to enhance the environmental awareness of CAVs, especially in complex scenarios like non-line-of-sight conditions. However, several challenges arise with the increasing volume of data generated by CAVs and infrastructure sensors. These challenges includes but not limited to:- Data Overloads in Communication Networks: The growing volume of data generated by onboard sensors leads to congested communication networks. This congestion can delay or prevent the transmission of crucial information in CPMs, impairing CAVs’ from receiving timely and relevant information, which may be essential for safe navigation and efficient operation.- Inefficient Congestion Control and Resource Allocation Methods: Current methods may not effectively manage the high volume of data traffic in C-ITS networks. They often fail to consider the criticality of certain data contextual scenarios that can lead to suboptimal utilization of network resources. This inefficiency can result in perception information being deprioritized or lost, further affecting the CAVs ability to accurately perceive and respond to their driving environments.This thesis, titled « Resilience of Cooperative and Augmented Perception of Autonomous Vehicles Connected by C-ITS, » focuses on the challenges of improving the resilience and quality of cooperative and augmented perception systems for CAVs. It proposes robust mechanisms to address key issues through two main contributions. The first, titled « Intelligent Cooperative and Augmented Perception Strategies for CAVs through Reinforcement Learning Techniques, » focuses on the development of intelligent strategies using reinforcement learning to optimize the cooperative perception of CAVs. These strategies allow CAVs to continuously adapt their data sharing to the current state of the environment, thus improving safety and efficiency in various driving conditions. The second contribution, « Adaptive Resource Allocation for Optimized Cooperative and Augmented Perception of CAVs, » addresses resource management in C-ITS systems. It proposes an adaptive allocation of communication resources in the ITS-G5 network, optimizing the exchange of information between CAVs and roadside infrastructure. These methods aim to reduce channel congestion and ensure reliable and real-time perception for CAVs, thus contributing to the improved resilience and quality of cooperative and augmented perception systems

Texto completoEtt nytt hot mot Public Key Infrastructures är den möjliga utvecklingen av storskaliga kvantdatorer som kan knäcka de asymmetriska kryptosystem som används idag. Ett flertal eventuellt kvantsäkra algoritmer har presenterats men de har än så länge inte sett mycket praktisk användning. Målet med detta examensarbete var att försöka identifiera eventuellt kvantsäkra signaturalgoritmer som skulle kunna lämpa sig för användning i Public Key Infrastructures idag. För att besvara forskningsfrågan gjordes en utredande litteraturstudie där relevanta signaturalgoritmer identifierades. Därefter prestandatestades de algoritmer som var implementerade i kryptografiska bibliotek. De algoritmer som prestandatestades var de hash-baserade algoritmerna XMSS och SPHINCS, flervariabel-baserade Rainbow och gitter-baserade BLISS-B. Resultaten visade att BLISS-B hade bäst prestanda och att prestandan var i nivå med RSA och ECDSA. Samtliga algoritmer hade emellertid relativt stora signatur- och/eller nyckelstorlekar. Eventuellt kvantsäkra algoritmer skulle redan idag kunna stödjas i Public Key Infrastructures eftersom många algoritmer finns implementerade i kryptografiska bibliotek. SPHINCS kunde rekommenderas när hög säkerhet krävs medan BLISS-B möjligtvis skulle kunna användas när lägre säkerhet kan tolereras i utbyte mot bättre prestanda. Största hindren för utbredd användning ansågs vara en brist på standardisering samt ineffektiva operationer jämfört med klassiska algoritmer och/eller tveksamma säkerhetsnivåer.

Texto completoOrganisationer vill vara ledande inom nya teknologier för att skapa unika tjänsteerbjudande och behålla drivkraft. Nya teknologier sätter press på organisationer som måste besvara dess utmaningar. Blockkedjetekniken är en omtalad teknologi som har fått stor uppmärksamhet de senaste åren, tekniken är komplicerad och i ständig utveckling. Syftet med denna studie är att identifiera utmaningar som blockkedjetekniken medför till organisationer samt vad organisationer ser för möjligheter med tekniken. Det kommer att diskuteras potentiella möjligheter som uppstår när organisationer överkommer utmaningarna och vad tekniken kan bidra med till digitala tjänster. I kombination med tidigare forskning och en kvalitativ studie som utförts hos en organisation som tillhandahåller digitala tjänster och som är intresserade att investera i blockkedjan har utmaningar och möjligheter identifierats.

Texto completoI dagsläget är ljusföroreningar en av de snabbast växande typerna av miljöföroreningar främst på grund av ökad användning av artificiellt ljus under dygnets mörka timmar. Det är framförallt fyra faktorer som bidrar till ljusföroreningar; bländning, himmelssken, ljusintrång och ljusansamlingar. Digitala skyltar blir allt vanligare i urbana miljöer och orsakar alla dessa typer av ljusföroreningar. Den nyaste typen av digitala skyltar visar en serie av väldigt ljusa bilder som byts med några sekunders mellanrum. Trots att digitala skyltar blir ett vanligare inslag i stadsmiljön finns det väldigt lite forskning om hur det påverkar människor som bor i anslutning till digitala skyltar. Majoriteten av forskningen som finns handlar om hur trafiksäkerheten påverkas. Det är viktigt att studera hur trafiksäkerheten påverkas men det är en miljö där människor vistas under kortare perioder. Ljus, och ljusföroreningar, kan påverka människor både fysiskt och psykiskt och därför måste bristen på forskning om hur boendemiljön påverkas åtgärdas. Syftet med studien är att undersöka hur boendemiljön påverkas av en digital skylt, och om den påverkas, hur förhåller de boende sig till det. Resultaten från studien kan användas för att diskutera riktlinjer för hur digitala skyltar ska planeras in i stadsmiljön för att minimera obehag. Att arbeta förebyggande är viktigt för att undvika en negativ påverkan på människors hälsa. För att undersöka om ljus från digitala skyltar påverkar människors boendemiljö utfördes en fallstudie med kvantitativ ansats. Studien utfördes i ett bostadsområde som låg i anslutning till en digital skylt. De boende kontaktades och ombads fylla i ett enkätformulär med frågor om sin boendemiljö samt attityd till den digitala skylten. Resultatet visar att de som bor närmast den digitala skylten påverkas mest. Hur boendemiljön påverkas beror till väldigt stor del på skyltens placering i förhållande till bostaden. Slutsatser som kan dras baserat på resultatet är att de respondenter som påverkas mest bor inom en 30-gradig vinkel sett från skylten. Många av de problem som uppstår på grund av digitala skyltar beror på okunskap och brister vid planeringen. Avsaknad av forskning och brister i de skyltprogram som finns gör det svårt att planera lämpliga installationer. För att orsaka minimalt obehag bör inga digitala skyltar placeras direkt framför ett bostadshus.

Texto completoThis work presents a critical analysis of the technology and law aspects of certified digital signatures, and their implementation in Brazil. We discuss and verify the competency rules that apply to the certification activity according to the legal nature of the digital certificate. A digital certificate is the instrument that secures the authenticity of an electronic document by means of a digital signature. According to the article 236 of the Brazilian Constitution, authenticity certifications are of exclusive competence of public notaries. Nevertheless, based on an under constitutional statute, digital certification has being conducted by the Federal Government thru its National Institute of Information Technology (Instituto Nacional de Tecnologia da Informação - ITI), who is responsible for the Brazilian public key root certification authority. We found that the statute that supports those activities (Medida Provisória 2.200-2/01) is unconstitutional, and therefore invalid and unenforceable, since it does not satisfy constitutional rules of material competency. Under a technology view, we find that the Managing Committee of the Brazilian Public Key Infrastructure explicitly defines the technology to be used in digital signatures. According to that ruling, until may 2006, among others, the MD5 hashing algorithm was used to generate digital signatures with statutory presumption of authenticity and integrity. Nevertheless, MD5 lost its technical usefulness in 2004, when it was broken, and became prone to fraud such as the generation of forged electronic documents. There is no doubt that Brazilian legislation gave legal value and probatory force to electronic documents signed using the already broken MD5 hashing algorithm that could very well had been forged. Digitally signed electronic documents can only be successfully used if legal rules and the technological aspects be fully understood and respected. Otherwise, the result will be high levels of uncertainty in law relations.

Texto completoIn this research we have aimed to explicit the politics of constitution of Caldas Aulete Digital Dictionary, starting from the comprehension of the functioning of the concept of language assumed in this dictionary, since this language is constituted by the tension between infrastructure and superstructure. We analyzed the functioning of the concept of language in the relationship between infrastructure and superstructure; we comprehended the concept of politics and its relations with meaning; we pointed the specificities and the conditions of production of Caldas Aulete Digital Dictionary, considering the reformulation of Houaiss Dictionary and Aurélio Dictionary in order to understand what relations are established between these different dictionaries, and we sought to present this space of reformulation in the articulation with social practices. The theoretical course developed was based on historical and dialectical materialism, also going through philological studies, structuralist linguistic studies, culminating in discursive studies. With Michel Bréal’s philological studies, we understand that language reflects the human being, its wills and desires, reinforcing the human condition of historical subject, responsible for changes in a language. The structuralist linguistic studies of Ferdinand de Saussure point to language as an abstract object, whose alterations occur in the displacement of the relation between the signifier and the signified, without any language external interference, thus limiting the language object to a stable system. Materialistic studies of Mikhail Bakhtin / Valentin Volochínov approach language as materiality, whose conditions of use refer to meaning, therefore, in functioning in the concrete reality of use. In discursive studies of Michel Pêcheux, the concept of language is articulated to the concept of discourse, to which the language serves as support for the accomplishment of the effects of meaning. The concept of politics taken from Hannah Arendt is articulated to the notion of freedom and it is the creation of the new, the unexpected, it is plural action and inherent to the human condition. To Jacques Rancière, politics is established with the damage and this damage undoes the police order instituted, breaking with the configuration of the society in which social classes are defined. In Michel Pêcheux’s theory, we observe that politics is related to the concept of discursive formation, as the words acquire their meaning inserted in such discursive formation, from the inscription of the subjects in a certain ideological formation. For the analysis, we selected entries which could contribute to illustrate the infrastructural and superstructural relations that are established in the production of the dictionary, as well as entries that could enable the relation with the concepts addressed. Such analysis also focused in the projects of Lexikon editor and allowed to present that in the initial project of the dictionary production an open work was aimed; a work of living language in the dictionary, that is, the functioning language in society, as a reflection of the practice of the subjects in infrastructure and superstructure, whose contribution was extended to the language speaking subjects, lay people when it comes to lexicographic criteria of the constitution of a dictionary. In the following project, redesigned, there is a return to classical and traditional dictionaries, as there is a control on the entries inclusion in the extent that the subject of organic forces can no longer contribute to the production of such dictionary, and the task of lexical establishment returns to lexicographers, subjects who are academically instructed to do so.

Texto completoThis thesis presents a contribution to the evaluation of digital communication in the operation of unmanned aerial vehicles (UAV) in the aeronautical environment. Aeronautical digital communication relates directly to the critical safety level required for controlling the air traffic flow by authorities and regulatory agencies, which are aimed at making communication uniform for all continents. There are several discussions about the safety critical level that digital communication between UAVs and ground control can display, always seeking to reduce exposure to risks inherent in the operation of such vehicles. In this context, the proposal of this thesis is to evaluate the safety in digital communication, through the use of fault injection for operations of UAV. This work describes the importance of analyzing the interference caused by faults in digital communication related to sending messages between the control agency and the UAV. There are also defined what types of faults cause a greater impact on communication as well as which parameters should be used to simulate communication faults. To answer the proposed evaluation, we used the simulated environment that combines the features of the aeronautical environment, called PIpE-SEC (Integrated Platform for Test Critical Embedded Systems), as well as the protocol CPDLC (Controller-Pilot Data Link Communications) to exchange digital messages.

Texto completoA sociedade contemporânea tem hoje como seu suporte vital uma rede global de comunicações composta por infraestruturas físicas e por sistemas digitais. As redes físicas formam um organismo de fluxos estruturante do território humanizado, enquanto as redes digitais criam uma realidade virtual omnipresente que também constrói o nosso mundo. Com base nestes sistemas desenvolveram-se novos paradigmas civilizacionais que reformularam conceitos clássicos de lugar, distância, tempo ou espaço, e gerou-se uma nova dimensão do real onde somos interlocutores em contacto e trânsito permanente num território ilimitadamente contínuo. O desafio passa por isso pela procura de um novo modelo de construção integrada e coesa do território, da urbe e dos espaços de habitar em consonância com os fluxos de pessoas, valores e dados em circulação. Este trabalho em particular promove esta nova ordem contemporânea através da integração morfológica e funcional da infraestrutura férrea com o tecido urbano de um ponto da cidade de Lisboa, em paralelo com a criação de um interface digital de contacto com a rede global. O projecto resultante, as plataformas em rede, surge assim como uma nova abordagem possível para o séc.XXI na reabilitação do sistema urbano pós-industrial, em que a realidade virtual é vista como uma oportunidade e as limitações técnicas de um canal ferroviário passam a ser um valor formal e simbólico do urbano. E forma-se um interface integrado entre o local e o global.
Contemporary society stands today on a vital mainstay of global communication networks composed of physical infrastructures and digital systems. The physical networks mold an interconnected flowing organism in which the human territory develops; parallel to this fact, digital networks also helps to build our world through an omnipresent virtual reality. Under these systems, new civilization paradigms transformed the classical concepts of place, distance, time or space, generating a new dimension of the real, embodying an endless territory in which we are the main protagonists. The challenge is therefore to search for a novice model of construction, one capable of blending in the urban tissue, through cities and spaces to inhabit, alongside human streams, values trade and exchanging data. This paper promotes this new contemporary order through a morphologic and functional juxtaposition of the railroad infrastructure from an exact location in Lisbon, apace with a digital interface within the global network. The final outcome, the networking platforms, posits itself as a feasible approach to the XXI Century, in rehabilitating the post-industrial urban system, where virtual reality is perceived as an opportunity and the railroad’s technical constraints an upright and symbolic urban asset. Hence the formation of an integrated interface between the local and the global.

Texto completoMuch of the contents and functionality of the traditional wallet, such as membership cards and payment solutions, have been replaced by smartphone solutions. Yet, in Sweden there is no smartphone based solution for ID cards that can be used in the same way as the physical ID card. This paper examines whether the Swedish authorities see a need for a smartphone based ID card solution and, if such a need is identified, suggests a model for how such a solution could be designed. To explore this topic, a literature review and three interviews with Swedish authorities (the E-identification Board, the Police Authority and the Transport Agency) have been conducted. The results of this report consists of three knowledge products: a demand analysis, a requirements specification and an infrastructure model. The demand analysis examines the need for a smartphone based ID card solution, as seen from the interviewed authorities' perspective. This analysis indicates that the authorities see a need for such a solution. The requirements specification consists of requirements for a smartphone based ID card solution, derived from the conducted interviews and Kim Cameron's The Laws of Identity (2005). The infrastructure model is designed to meet these requirements and describes how a smartphone based ID card solution could be designed to fit into the Swedish infrastructure for digital identity management. The model is also designed to follow the design rules for information infrastructure development derived by Hanseth and Lyytinen (2010) and shows that the development of a smartphone based ID card solution in Sweden is technically feasible.

Texto completoUganda är ett låginkomstland i östra Afrika där både ekonomisk och social utveckling har frodats sedan lanseringen av mobiltelefoni (Deloitte, GSMA, and Cisco, 2012). Att ugandier är positivt inställda till utvecklingen och användningen av mobilteknologi är väsentligt för att den internationella handeln ska kunna växa. I dagsläget finns olika faktorer som hindrar utveckling i landet (African Development Bank, 2014). Det saknas aktuell forskning gällande Ugandas behov av ett adressystem. Den här uppsatsen är baserad på intervjuer med 6 personer som har arbetat med affärsklimat och infrastruktur. Denna kvalitativa studie undersöker hur ett digitalt baserat adressystem kan bidra till en förbättrad handel för Uganda genom förbättrad tidseffektivitet, fler möjligheter, tillgänglighet, samarbete och leveranser. Lanseringen av fysiska adresser har börjat i huvudstaden, Kampala. Däremot tyder resultatet från den här uppsatsen på att ett nationellt etablerat, nåbart och flitigt använt adressystem skulle gynna Ugandas ekonomi. Slutsatsen är att levnadsstandard, affärsklimat, den offentliga sektorn, entreprenörskap, marknader, tjänster och handel skulle främjas på ett hållbart sätt av en rikstäckande implementering av ett adressystem. Det sker genom förbättrad infrastruktur, leveranssystem, navigationsmöjligheter samt tillgänglighet till tjänster och transport. Detta förväntas resultera i ökad tids- och kostnadseffektivitet för dagliga affärsaktiviteter.

Texto completoIn a report financed by Smart Built Environment it was stated that there are possibilities to improve quality and reduce cost in the finished product through digital solutions in the construction industry. One area where digitization has got a high impact is in the use of digital tools on the construction site (Bygg 4.0, u.å.). Digital tools are defined as software and applications suited for the construction industry. The purpose of this thesis was to map out the digital tools used in Skanska's production and to compare the use of digital tools within the business areas infrastructure and commercial building. The study focuses on how the use of digital tools is encouraged through strategies and objectives in Skanska's organization. The method for collecting material was a literature study of theory, a quantitative survey and qualitative interviews. The survey focused on the use of digital tools and the interviews on Skanska's employees perception on Skanska's work with digitization. The results of the study show differences in the extent that the digital tools are used within the business areas. The results of the quantitative study show that the business area commercial building uses the digital tools to a greater extent. The reason for this is that the business area commercial building works proactively through recommendations such as Basnivå Hus, Projekt i världsklass and Smarta projekt. The business area commercial building also has a role called digital leader in every project, who are supported by a digital coach in every region. The business area infrastructure does not have an equally established foundation, since only Projekt i världsklass is the starting point for digital work within the business area. There are also no digital leaders in projects within the business area. This role arises organically through committed individuals with good knowledge of digital tools. The business area commercial building has a well-established system for working with digital tools, which means that the business area has come further than the business area infrastructure.
